Hi,

When I use the YAML Component in my project, I use $dumper = new Symfony\Component\Yaml\Dumper();

Then I do $dumper->dump($myarray, 2).

When $myarray is not empty, the YAML file generated is nicely indented.

When $myarray is empty, the YAML file generated is { } instead of an empty file.

I think it's a forgotten feature.
